javax.xml.ws.WebServiceException: java.lang.NoClassDefFoundError: Could not initialize class org.apache.log4j.LogManager

I created a JAX WS service using annotations and used ANT to create .war and added log4j under WEB-INF/lib folder but while deploying the application in weblogic 10.3.0 I am getting the below error. I even tried by copying the log4j-1.2.8 under /lib and /lib but didnt work. But without log4j enabled I am able to successfully test the web service. Any help is appreciated.

You need to actually add it to your classpath (how to do that differs from IDE but in most IDE's you can do that under the 'Libraries' project property
